Abstract

A wrap for smoking articles, which encloses a group of smoking articles and has, at the top and at the front, a first extraction opening obtained through the wrap by means of a “U”-shaped through cut. The first extraction opening is normally closed by a reusable closing portion, which consists of the part of the wrap surrounded by the through cut and it can be lifted to free the first extraction opening and then lowered again to engage the first extraction opening. A support element is comprised, which is arranged inside the wrap at the first extraction opening, it is glued to the wrap at least by means of a re-stick glue, and it has a second extraction opening, which is smaller than the first extraction opening and it is entirely contained in the first extraction opening.

First claim

The invention claimed is:

1. A wrap ( 3 ) for smoking articles, which encloses a group ( 14 ) of smoking articles, is obtained by folding a wrapping sheet ( 26 ) of rectangular-shaped wrap around the group ( 14 ) of smoking articles, once folded the wrapping sheet is stabilized by means of heat- sealing, and the wrapping sheet has, at a top and at a front, a first extraction opening ( 15 ), which is obtained through the same wrap ( 3 ) by means of a first U-shaped through cut ( 16 ) and crosses the wrapping sheet ( 26 );
wherein the first extraction opening ( 15 ) is normally closed by a reusable closing portion ( 17 ), which consists of the part of the wrapping sheet ( 26 ) surrounded by the first through cut ( 16 ) and the part of the wrapping sheet surrounded by the first through cut can be lifted to free the first extraction opening ( 15 ) and then lowered again to engage the first extraction opening ( 15 );
wherein the wrap ( 3 ) for smoking articles comprises a support element ( 18 ), which is arranged inside the wrap ( 3 ) at the first extraction opening ( 15 ), the support element is in direct contact with the group ( 14 ) of smoking articles without the interposition of other elements, the support element is smaller than the wrapping sheet ( 26 ), extending only at a front wall and an upper wall of the wrap ( 3 ), the support element is glued to the wrapping sheet ( 26 ) by means of a re-stick glue ( 20 ), and has a second extraction opening ( 19 ), which is smaller than the first extraction opening ( 15 ) and is entirely contained in the first extraction opening ( 15 );
wherein the wrap ( 3 ) for smoking articles comprises an intermediate element ( 32 ), which is interposed between the wrap ( 3 ) and the support element ( 18 ), is stably and permanently connected to the wrapping sheet ( 26 ) by means of a first permanent glue ( 33 ), and is glued to the support element ( 18 ) by means of the re-stick glue ( 20 ).

2. The wrap ( 3 ) for smoking articles according to claim 1 , wherein the support element ( 18 ) is arranged between the wrap ( 3 ) and the group ( 14 ) of smoking articles.

3. The wrap ( 3 ) for smoking articles according to claim 1 , wherein the re-stick glue ( 20 ) determines a gluing, which, in use, is never separated between the part of the wrapping sheet ( 26 ) outside the first extraction opening ( 15 ) and the support element ( 18 ) and the re-stick glue determines a gluing, in use, separable between the closing portion ( 17 ) and the support element ( 18 ) only around the second extraction opening ( 19 ).

4. The wrap ( 3 ) for smoking articles, according to claim 1 , wherein the re-stick glue ( 20 ) is absent or neutralized at a lifting part of the closing portion ( 17 ) arranged in the front wall of the wrap ( 3 ) so that the lifting part of the closing portion ( 17 ) never adheres to the support element ( 18 ).

5. The wrap ( 3 ) for smoking articles according to claim 1 , wherein a second permanent glue ( 22 ) is provided, which is arranged between the wrapping sheet ( 26 ) and the support element ( 18 ) on the outside of the closing portion ( 17 ) in addition to the re-stick glue ( 20 ) to increase the bond with respect to the presence of just the re-stick glue ( 20 ).

6. The wrap ( 3 ) for smoking articles according to claim 1 , wherein the support element ( 18 ) has a through hole, which defines the second extraction opening ( 19 ) and is made by cutting a central part of the support element ( 18 ) along a second through cut ( 23 ), which is closed in a ring shape.

7. The wrap ( 3 ) for smoking articles according to claim 1 , wherein;
the support element ( 18 ) has a first movable part ( 24 ), which is arranged at the closing portion ( 17 ), is permanently glued to the closing portion ( 17 ), and is delimited from the remaining part of the support element ( 18 ) by a second U-shaped through cut ( 23 ).

8. The wrap ( 3 ) for smoking articles according to claim 7 , wherein a third permanent glue ( 25 ) is provided, which is arranged between the first movable part ( 24 ) of the support element ( 18 ) and the closing portion ( 17 ).

9. The wrap ( 3 ) for smoking articles according to claim 1 , wherein the intermediate element ( 32 ) has a third extraction opening ( 34 ), which is smaller than the first extraction opening ( 15 ) of the wrap ( 3 ) and larger than the second extraction opening ( 19 ) of the support element ( 18 ) and the intermediate element is entirely contained in the first extraction opening ( 15 ) of the wrap ( 3 ) and externally surrounds the second extraction opening ( 19 ) of the support element ( 18 ).

10. The wrap ( 3 ) for smoking articles according to claim 9 , wherein the third extraction opening ( 34 ) of the intermediate element ( 32 ) is closer to the first extraction opening ( 15 ) of the wrap ( 3 ) and further from the second extraction opening ( 19 ) of the support element ( 18 ).

11. The wrap ( 3 ) for smoking articles according to claim 9 , wherein the intermediate element ( 32 ) has a second movable part ( 35 ), which is arranged at the closing portion ( 17 ), is permanently glued to the closing portion ( 17 ), and is delimited from the remaining part of the intermediate element ( 32 ) by a third U-shaped through cut ( 36 ).

12. The wrap ( 3 ) for smoking articles according to claim 11 , wherein the support element ( 18 ) has a first movable part ( 24 ), which is arranged at the closing portion ( 17 ), is permanently glued to the closing portion ( 17 ) with the interposition of the second movable part ( 35 ), and is delimited from the remaining part of the support element ( 18 ) by a second U-shaped through cut ( 23 ).

13. The wrap ( 3 ) for smoking articles according to claim 11 , wherein along the first through cut ( 16 ) and along the third through cut ( 36 ) the first permanent glue ( 33 ) is absent or neutralized.

14. The wrap ( 3 ) for smoking articles according to claim 1 , wherein the re-stick glue ( 20 ) is applied to the intermediate element ( 32 ).

15. The wrap ( 3 ) for smoking articles according to claim 1 and comprising a reinforcement element ( 28 ) consisting of cardboard or rigid paperboard, the reinforcement element is arranged inside the wrap ( 3 ) in contact with the group ( 14 ) of smoking articles and the reinforcement element is independent and separate from the support element ( 18 ).

16. The wrap ( 3 ) for smoking articles according to claim 1 and comprising a reinforcement element ( 28 ) consisting of cardboard or rigid paperboard, the reinforcement element is arranged inside the wrap ( 3 ) in contact with the group ( 14 ) of smoking articles and the reinforcement element is integrated with the support element ( 18 ).

17. The wrap ( 3 ) for smoking articles according to claim 1 , wherein the support element ( 18 ) is provided with pre-weakened folding lines at edges of the wrap ( 3 ).
